The lake is about 160 miles wide and about 350 miles long. It has a surface area of 31,699 square miles, and water volume of 2,900 cubic miles. The deepest spot in Lake Superior is 1,300 feet beneath the surface, making a whole freeze very uncommon. Lake Superior possesses enormously clear water, with an average underwater visibility of 27 feet. Like all of the Great Lakes, Lake Superior is prone to lake effect snow, but the weather is normally reasonable, with warmer temperatures than inland during the year. Winter temperatures in the region of the lake rarely fall below minus 30 degree Fahrenheit, well above inland temperatures. June and July are calm months, while October and November are prone to storms. During the majority of winters, the lake is 40 to 95 percent covered with ice, though it hardly ever fully freezes. The last time Lake Superior froze over completely was in 1997, and it almost totally froze in 2003. The average water temperature for Lake Superior is 40 degrees Fahrenheit lower than the other Great Lakes, which are farther south. The water temperature throughout the summer month’s average is about 55 degrees Fahrenheit, but surface temperatures achieved a record of 68.7 degrees Fahrenheit in August of …show more content…

With the ship weighing that much, it sat lower in the water compared to most ships which made it more helpless to an overly large wave. In the official description, it says that the hatches to the cargo area may have been defective, which would lead to an unexpected change to the cargo that tipped over the
